Check of ITMy Elliptical Baffle Current Alignment
B. Weaver, J. Oberling, T. Shaffer
This morning we took a quick look at the ITMy elliptical baffle (in BSC2) to get an idea of where its alignment is currently at before the baffle re-working currently scheduled for later this week. I set up and aligned the aux alignment laser assembly in front of ITMy, TJ moved the target assembly from PR3 to SR3 and we aligned the beam to it, and Betsy installed the elliptical baffle alignment target (D1102073). After this was complete we found that the ITMy elliptical baffle was almost perfectly aligned; the laser from the aux alignment assembly was centered on the crosshairs of the baffle target.
Betsy took several pictures and will post them as a comment to this alog.
The beam looks to be centered on the baffle target to within a mm (tol is many mm's). So, on we go with rebuilding it this week!
